Display-Aided Head Tracking

If you've ever used Apple's PhotoBooth software to take a picture of yourself with the webcam built into the screen, you'll notice the display turns white when the picture is taken. The idea is to use the monitor as a flash bulb - it illuminates your face and produces a better image in low-light conditions. […]

Wave field synthesis graphical simulation

This is a Processing sketch/Java applet that simulates wave field synthesis. A virtual source follows the position of the mouse cursor. It's useful for visualizing the behavior and limitations of WFS. Right now it lets you change parameters of a line array, and I'll try to extend it to simulate other array configurations. Key Commands: […]

Wave field synthesis build progress

Spent the week building speakers. 12 modules complete (48 speakers). Have yet to wire them all up. Still waiting on a few power adapters.

Pandora and Flash Player

December 2010. I am using a Pentium 4 2.2 GHz machine, Chrome browser, and playing some Pandora tunes. When Pandora is in the foreground, Flash Plugin is using 50% CPU time. When I switch to another tab, Flash cools down to 10% CPU time. So just a tip there, hide that Pandora if you want […]

Wave field synthesis first speaker module

I built the first WFS speaker module and it turned out well. Now I have to build 11 more before Christmas. Just like Santa's workshop 🙂

Wave field synthesis array plans

Plans are coming along for construction of the ALMWFSLA (pronounced "almwfslah"), or Absurdly Large Modular Wave Field Synthesis Loudspeaker Array. The modules will be 18" x 4.5" with an open-back enclosure. This will allow for a 4'-6" x 3' plane array, a full surround line array 11 feet in diameter, and many more fascinating configurations. […]

What’s Wrong with the University of Miami IT Policy

The University of Miami campus network and IT policy has problems. It's a big part of life for college students and faculty, so this is a call to action. Here are a few frustrating things that the IT department at Miami should try to improve. 1) University e-mail forwarding is prohibited You aren't allowed to […]
